2005 V6 mustang. The A/c stopped blowing cold the day I picked the car up from having the clutch replaced. Main clutch, not the compressor clutch. My brother checked the Freon levels and they were fine. I've checked all of the fuses. I had it looked at this morning by the high school shop teacher(don't laugh, it was free) He switched out the relay with the high beam relay and it started blowing cold. He switched them back and it was still blowing cold. I picked the car up this afternoon and it's back to the same hot air. The thing is, the high beams work with the "faulty" relay, so I don't think that's my problem. I've checked all of the fuses and they are good. I'm having other electrical issues as well. The gas gauge either reads empty or way past full, my turn signal will periodically blink fast and at the same time, my temp gauge pegs at hot. Both of those problems go away and come back at the same time. I have had the issue with leaking from behind the glove box. Any suggestions? I just had my suspension redone and dumped about a grand in that.

Possibly smart junction box issues from water.....

well for 1 i know your car dont have Freon. Check all your grounds. If they didnt reconnect 1 one of the grounds or left it lose it can cause all sorts of control issues. Id lean that direction from what it sounds. check back of engine, frame rails, firewall. etc...

Depending on how the freon was checked, I would suspect a bad low pressure switch.
